Dang...I'm taking the wrong drugs! I do not recall seeing colored flashes when in total darkness (lava tubes in NE CA)...or else they did not make an impression on me. I'll have to give it another go next time I photograph over there. It might be due to the significant amount of time I have spent developing sheet film in trays. My brain is attuned to the darkness and may not feel the need to create sights when there are none to see -- except --... or anesthesia...
I was in total blackout (underground mine with no light source at all) several times. No grey was noticed but profound experience of shooting colored light flashes.
I still love that I 'see' my hands while developing film in darkness. I believe muscle positioning tells my brain where my hands are, and my brain does the rest. I can 'see' my hands but not what they may be holding.
